DRENCHlNG-BIT.

SPECIFICATION forming part of Letters Patent No. 509,968, dated December5, 1893.

Application filed February 25, 1893. Serial No. 463,744. (No model.)

.To aZZ whom it may concern:

Be it known that I, THOMAS E. SWAN, a citizen of the United States,residing at the city of Atlantic, in the county of Cass and State ofIowa, have invented certain new and useful Improvements in Bridle-Bits;and I do declare the following to be a full, clear,'and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon. which form a part of this specification.

My invention relates to improvements in bridle-bits and it consists inthe peculiar construction and combination of the parts that will be morefully set forth hereinafter and particularly pointed out in the claim.

The object of my invention is to provide a bridle-bit which will performthe oifice of an ordinary bridle-bit, and which can also be utilized inthe treatment of the various diseases to which the throats and mouths ofhorses are liable. I attain these objects by the device illustrated inthe accompanying drawings in which-,-

Figure 1, is a perspective view of my improved bridle-bit having a partof the mouth piece broken away to show the construction within the mouthpiece. Fig. 2, is a perspective view of a modified construction of thebridle-bit having a part of the mouth piece broken away showing thesupports for the absorbent materialwith the absorbent material removedtherefrom. Fig. 3, is a detailed perspective view of the threaded plughaving the ring and the absorbent material support attached thereto.Fig. 4, is a detailed perspective view of the threaded plug having thering and absorbent material support secured thereto, and of theabsorbent material secured to its support. Fig. 5,is a cross section ofthe bridle-bit taken on the broken line 00 0a, in Fig. 1.

Similarletters refer to similar parts throughout the several views.

A, is the mouth piece of the bit which is made hollow and has a numberof small perforations d, formed through its sides, through whichmedicine contained within the mouth piece, or its vapor, may escapeintothe horses mouth.

(3 O,are the rings into which the headstallstraps and the reins arebuckled.

B B, are plugs which stop the ends of the mouth piece A. They each haveapertures f, through which the rings loosely pass. The inner end a, ofeach plug is threaded and made of suitable size to fit the innerdiameter of the mouth piece which has its innersurface threaded at itsends to receive the inner threaded ends of the plugs. hen thebridle-bitis constructed with a mouth piece as shown in Fig. 1, the plugB, can be made permanent and integral with the mouth piece if desired.

D, is a support for the absorbent material which is firmly secured atits outer end to the inner end of the plug B, and preferably madeintegral therewith, and it consists of a rod which extendslongitudinally along the hollow within the mouth piece A, provided withthe apertures e, and b, and having the point g, at its inner end.

E, is a piece of sponge having the support D, passing longitudinallythrough it. Instead of sponge any other absorbent material can beemployed.

F, is a flexible band by means of which the sponge, or absorbentmaterial is securely bound to the support D. The middle portion of theband is within the aperture 12, and the end portions pass through theaperture e, in opposite directions and are brought together on top ofthe support and tied by the knot h.

In the modified construction of the bridlebit shown in Fig. 2, the mouthpiece consists of two sections m, and n, hinged together at their innerends in the ordinary manner, each section being provided with anabsorbent material support D. The support D, is made pointed so that itreadily pierces the absorbent material fixed thereon. The diameter ofthe absorbent material E, is made somewhat less than the inner diameterof the mouth piece so that there is a space between the outer surface ofthe absorbent material and the inner surface of the mouth piece.

By unscrewing the plug having the support attached thereto, the supporthaving the sponge, or absorbent material mounted thereon, can be easilywithdrawn from the mouthpiece and the sponge saturated with medicatedliquid, and then inserted within the mouth-piece and secured therein byscrewing the plug into the end of the mouth-piece. If the bit be theninserted in a horses mouth the Vapor from the medicated liquid willescape through the perforations (Z, into the horses mouth, and thesalivafrom the horses mouth will pass in and out of the perfora tions d,and around and about the surface of the sponge, or absorbent material E,and abstract the medicated liquid therefrom and convey it into thehorses mouth.

It is evident that the bit can be used as an ordinary bridle-bit whendesired.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-
